# Quote of the Week

<!-- QOTW goes here -->
> Well, the answer is basically yes. Our firmware is all Rust. Every component of our autonomy stack is Rust. Our app is 50% in Rust. And, our visualization tools are in Rust. Our production tools are in rust. The production QC software, which we ship to China, is in rust. Our internal websites are in rust. It's rust all over. We’ve drank the Rust Kool-Aid. In fact, there is no Python installed on the robots. This is not to dis Python at all, but it’s just simply not there.
>
> We use Python for neural network training. But Python is boxed to that. Everything else is Rust. And, the advantage of using Rust exponentially builds up.
